I would really appreciate advice on how to get past the folowing build failure, and/or suggestions on alternate approaches. Thanks!

Building ROS according to the directions at http://wiki.ros.org/kinetic/Installation/Source, the following command failed

$ ./src/catkin/bin/catkin_make_isolated --install -DCMAKE_BUILD_TYPE=Release

After I got the error, I tried to provide the missing config.cmake files by installing shiboken2 and pyside2 at the suggestion of the build output, with these commands:

$ sudo apt-get install shiboken2
$ sudo apt-get install libpyside2-5.11
$ sudo apt-get install libpyside2-py3-5.11

After this I still couldn't find the missing config.cmake files using

$ sudo find / -name Shiboken2Config.cmake

etc., so I couldn't add their paths to CMAKEPREFIXPATH which in any case doesn't exist yet.
